SAFETY-PIN.

Specification of Letters Patent.

Patented May 8, 1906.

Application filed December 24. 1898. Serial No. 700,198.

T0 at whom, it may concern:

Be it known that I, THERoN S. CARROLL, a citizen of the United States, residing at Winsted, in the county of Litchfield and State of Connecticut, have invented new and useful Improvements in Safety-Pins, following is a specification.

This invention relates to safety-pins, the purpose of the improvement being to provide a safety-pin which will be comparatively narrow or flat, and in carrying my invention into effect I use a coilless pin-bar and provide means for reinforcing such a pin-bar at its bent portion, and in the make-up of a safety-pin in accord with my invention the pin-bar is formed of spring-wire which is bent upon itself so that the members on each side of the bend will be normally in the same plane, the member of the pin-bar that engages the pin-point-guard being pointed, the other member having attached thereto a sheetmetal guard of such construction that it is adapted to engage the segmentally-bent portion of the pin-bar and to extend across and in advance of such part to reinforce the bend in the pin-bar and to prevent fabric or material in which the pin-bar is inserted catching in the reinforcing part or passing beyond the bend in the pin-bar.

Another object of my invention is to provide a safety-pin with a rigid back member the transverse dimensions of which will not greatly exceed the diameter of the pin-bar; and with such ends in view my invention consists in the construction and combination of the parts, as will be set forth and claimed.

In the accompanying drawings, which illustrate one form of my invention, Figure 1 is a side elevation showing the complete safety-pin in an 0 en position. Fig. 2 is a plan view of the b ank fromwhich the back, the pin-point shield, and the guard are formed; and Fig. 3 is a sectional view on the line 3 3 of Fig. 1.

In the make-up of a safety-pin, as illustrated, the blank A, from which the back member is formed, is stamped from sheet metal and comprises a part a, the ends having projecting parts a and M, the part a and its end portions being bent or folded on the dotted lines shown on Fig. 2. The end of the blank A that is provided with the part a has projections or offsets a and a and such part a is shaped so that its outer edges will correspond with the curvature or bend of the pin-bar and is of sufficient width to extend of which the considerably in advance and across such bent part of the pin-bar. The inner edge of the art a is preferably concave, as such shape will tend to lead the fabric through which the pin-bar is passed away from the parts which embrace the curved portion of the pin-bar, and such spanning member forms an efiicient guard and brace.

The shield a is formed on the other end of the blank from the guard and brace and carries a part C, that lies between the ends of the back and the pin-point shield, the

art being held securely between such parts. The plate C has a tongue 0, the end of which may be beveled, such tongue being of a material that will give slightly to side pressure, and the plate is held in place by swaging the outer ends of the shield upon the plate or by soldering.

The diverging members of the coilless pin bar lie normally in the same plane, and the se mentally-bent portion of the pin-bar is he d by the bent-over or swaged parts of the brace to limit or restrain and reinforce the pin-bar at its bend.

A safety-pin made in accord with my in vention has a pin-bar formed of spring-wire which is bent upon itself to form normally diverging or angularly-disposed members which lie in the same plane, one of the members being pointed, the opposite member of the pin-bar having connected thereto a pinpoint shield. The segmentally-bent portion of the pin-bar is reinforced by a part which extends across and in advance of such bent part of the pin-bar to provide restraining means which will prevent undue bending of the return-bend of the pin-bar.

Having thus set forth my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A safety-pin comprising a pin-bar and a pin-point shield for the pointed end of the pinbar, the pin-bar having a segmental bend without a coil, the pointed end of the pinbar normally tending to move away from the pin-point shield when disengaged therefrom,

and means engaging the pin-bar at the segmental bend and acting to limit said movement of the pointed end of the pin-bar and also acting as a stop to prevent fabric through which the pin-bar is inserted passing to and around said bent part of the pin-bar.

2. A safety-pin comprising a pin-bar and a pin-point shield for the pointed end of the pinbar, the pin-bar having a bend without a coil, the pointed end of the pin-bar normally tending to spring or move away from the pin-point shield when disengaged therefrom, and a part that extends across the pin-bar in advance of the bend therein such part having integral therewith an embracing portion,

said part acting to limit the movement of the pointed end of the pin-bar and as a stop to prevent fabric through which the pin-bar is inserted passing to and around the bent part of the pin-bar.

3. A coilless safety-pin embodying a pinbar formed of spring-wire which is bent segmentally upon itself to form normally diverging members which lie in the same plane, and a back member having at one end a pinpoint shield and at the other end a reinforcing part which extends in advance of the segmentally-bent part across the space between the members of the pin-bar and engages such part of the pin-bar to reinforce its segmentally-bent portion.

4:. In a safety-pin, a pin-bar having a bent portion, a sheet-metal back to which the bent portion of the pin-bar is attached, a flat brace on said back which extends in the same direction as the bent portion of the pin-bar, a stop or lug formed by bending the end of the brace to overlie a portion of the pin-bar; whereby the pin-bar is sustained and movement at its bent portion is limited.

5. In a safety-pin, the combination with a pin-bar which is bent back upon itself to form two members which lie in the same plane, of a back member which is bent upon itself to provide at one end a pin-point shield, one member of the pin-bar being attached to the end of the back farthest from the shield, a brace which rojects from one side of the back and para lels the bent portion of the pin-bar, the brace having its end bent toward the back to form a stop or lug which overlies that bent portion of the pinbar which is farthest from the back, for the purpose set forth.

6. A safety-pin embodying a pin-bar formed of spring-wire which is bent upon itself to form normally diverging members which lie in the same plane and a back memher having at one end a pin-point shield and at the other end a part the end of which is bent toward the back member to overlie the in-bar and limit its spring movement away from the back. In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
